Title: The Platelet Destruction Site in Thrombocytopenic Purpuras
Abstract: SUMMARY The site of sequestration of 51 Cr‐labelled platelets has been studied in 465 subjects, of whom 317 suffered from idiopathic thrombocytopenic purpura. The validity of the method was demonstrated in several ways: a given subject usually showed the same site of platelet sequestration when investigated more than once even after a long interval; there were characteristic and very different platelet sequestration curves in the thrombocytopenias due to bone marrow hypoplasia, hypersplenism or ITP; and there was a correlation between the preoperative in vivo results and the radioactivity found in the spleen after splenectomy. In ITP the destruction of labelled platelets was more often splenic in children and in patients whose thrombocytopenia responded to steroid therapy. There was a perfect correlation between the site of platelet destruction and the platelet rise immediately after splenectomy. There was a good correlation between the site of platelet destruction and the long‐term effectiveness of splenectomy.
